The remote device is missing a vendor-supplied security patch.
A vulnerability exists in the Session Initiation Protocol (SIP)
implementation in Cisco IOS Software that can be exploited remotely to
cause a reload of the Cisco IOS device.
Cisco has released free software updates that address this
vulnerability. There are no workarounds available to mitigate the
vulnerability apart from disabling SIP, if the Cisco IOS device does
not need to run SIP for VoIP services. However, mitigation techniques
are available to help limit exposure to the vulnerability.
